  - Merge "xci: installer: osa: Fix status report when bootstrapping OSA"
  - xci: installer: osa: Fix status report when bootstrapping OSA

    Fixes the following ansible-lint warning

     [WARNING]: While constructing a mapping from /home/devuser/releng-
    xci/xci/installer/osa/playbooks/configure-opnfvhost.yml, line 113,
    column 7,
    found a duplicate dict key (args). Using last defined value only.

    We also remove the changed_when value since we now use 'args' to get
    proper status report.
